The paper considers a promising class of polymer materials - thermoplastic vulcanizates (TPV), which have the properties of elastomers, but can be processed by advanced technology of processing of thermoplastics. The formulation and technology of producing TPV based on frost-resistant propylene oxide rubber and polypropylene modified with ultra-dispersed additives obtained by joint mechanical activation of aluminum powders or natural zeolites with a plasticizer have been developed. The structure of the materials obtained are considered by electron microscopy and DSC. It is shown that the introduction of ultra-dispersed additives leads to a significant improvement in the physico-mechanical characteristics, frost resistance coefficient and oil resistance of TPR, which is associated with better dispersion of the elastomeric phase particles and its more uniform distribution in the polypropylene matrix.
